How long the shunt tube needs to be measured and cut before surgery and set aside.

Hearing his words, Song Xuelin turned his head and looked at him, his eyes incredible.

Without Senior Brother Huang's head knocking, it was obvious that the talented man in Beidu's eyes were even more insulting. He was not saying that he was stupid, but thinking about whether he came from an alien planet.

Student Wei's face turned red and his eyes were red, and he said, "You have something to say."

I asked how long the insertion was. You told me how long the pipe from the head to the abdomen was. Is the latter's insertion? The latter's movement was to penetrate. This was clearly a communication between Earth and Alien languages. The chicken and duck talk.

.

Student Wei wanted to hold his head and run away with his hands: Well, why did he come to the neurosurgery internship to find abuse? And what was abused is because of his IQ.

No department is like neurosurgery.

No, no, it’s just the terrifying group of Senior Brother Cao. Other groups, like Deputy Director Lu’s group, are neurosurgeons, and can be called the idiot group by Little Idiot Brother Huang.

How long is the insertion? It refers to the length of the shunt tube reaching the lateral ventricle after the head is opened. The shunt tube is connected in several pieces. The highlight is definitely at the end of the tube in the head at the beginning. Because the head is compared to other parts of the human body.

More complicated, a little mistake would be irretrievable. This is the scope of business that neurosurgeons are best at.

Specifically, first, after this shunt tube enters the human brain, it must accurately reach the lateral ventricle instead of mistakenly entering the brain parenchyma or other important functional areas. To this end, the precise length of the shunt tube insertion must be placed in the first place.

One. Second, the tip of the shunt tube should be placed directly in front of the inter-ventilator hole.

The interventricular hole is a pile of channels connecting the left and right ventricles and the third ventricle, located at the anterior part of the lateral wall of the third ventricle. The tip of the shunt tube is placed in this position accurately, which can avoid the two daily blockages of the choroidal plexus and glial hyperplasia.

The blockage blocks the side hole of the shunt pipe.

A group of classmates turned around and saw the disinfected and packaged diverter pipe prepared by the equipment nurse. The first time I saw it, I couldn't help but be surprised: Such a thin tube?

The drainage tubes that are usually seen in other clinical departments are mostly thicker. A thick drainage tube is beneficial and is easy to drain out liquid and avoid blockage.

The cerebrospinal fluid shunt is different. The first thing is that it is a shunt tube that needs to be placed in the human body for a long time. As long as nothing happens, it will not be taken out. It is long and has a very long end in the human body.

Doctors must consider the comfort of the human body. They cannot say that they have a thick piece of things and such a long thing placed in the human body makes the patient feel uncomfortable all day long.

The shunt tube is a thin silicone tube in diameter, both adults and children.

Therefore, it is better to see at first sight than to hear. Most of the things mentioned in textbooks are generally discussed in general, and some things cannot be understood even if they are said. If you need to see the real thing in clinical practice, you will suddenly see the darkness of the will of light: So that's it.

It is conceivable how difficult it is to accurately land the head of a pipe in a designated position.

The first step is to calculate the exact length.

What calculations are made?

It only depends on the current films, plus the doctor's own experience and calculation ability. The predecessor can refer to the doctor's hand feeling. Xie Wanying believes that she does not have it, and she is definitely not as good as Senior Brother Cao, so she can only calculate it with her own brain.

"The depth of the forehead path is about 7.2. If it is a pillow-back approach, it is about 10.5." Xie Wanying said.
